Delayed-tackifier coated particulates and methods relating thereto

Abstract

Delayed-tackifier coated particulates and treatment fluids comprising delayed-tackifier coated particulates wherein the tackifier is associated with a surfactant. The treatment fluids may be used in methods that include providing a treatment fluid that comprises an aqueous base fluid and a delayed-tackifier coated particulate and introducing that treatment fluid into a wellbore penetrating a subterranean formation. Once within the formation, forming a particulate pack, wherein the particulate pack is a gravel pack along a portion of the wellbore, a proppant pack within a portion of the subterranean formation, or both.

The invention claimed is:

 introducing the treatment fluid into a wellbore penetrating a subterranean formation; and, 
 forming a particulate pack within the subterranean formation, wherein the particulate pack is a gravel pack along a portion of the wellbore, a proppant pack within a portion of the subterranean formation, or both. 
 
     
     
       2. The method of  claim 1  wherein the degradable surfactant comprises at least one selected from the group consisting of a cationic surfactant, a nonionic surfactant, and any combination thereof. 
     
     
       3. The method of  claim 1  wherein the delayed-tackifier coated particulate is formed by at least one method selected from the group consisting of: dry-coating the particulate with the tackifier and the degradable surfactant simultaneously; dry-coating the particulate with the tackifier and then wet-coating the particulate with the degradable surfactant; wet-coating the particulate with the tackifier and the degradable surfactant simultaneously; and, wet-coating the particulate with the tackifier and then wet-coating the particulate with the degradable surfactant. 
     
     
       4. The method of  claim 1  wherein the delayed-tackifier coated particulate is present in an amount ranging from about 0.25 pounds per gallon to about 30 pounds per gallon of the treatment fluid. 
     
     
       5. The method of  claim 1  wherein the treatment fluid is foamed. 
     
     
       6. The method of  claim 1  wherein the treatment fluid further comprises at least one additive selected from the group consisting of a salt, a weighting agent, an inert solid, a fluid loss control agent, an emulsifier, a dispersion aid, a corrosion inhibitor, an emulsion thinner, an emulsion thickener, a viscosifying agent, a gelling agent, a foaming agent, a lost circulation material, a pH control additive, a breaker, a biocide, a crosslinker, a stabilizer, a chelating agent, a scale inhibitor, a gas hydrate inhibitor, a mutual solvent, an oxidizer, a reducer, a friction reducer, a clay stabilizing agent, and any combination thereof. 
     
     
       7. The method of  claim 1  further comprising:
 introducing a pad fluid into the subterranean formation before introducing the treatment fluid, wherein introducing the pad fluid is at a pressure sufficient to create or extend at least one fracture in the subterranean formation. 
 
     
     
       8. The method of  claim 1  further comprising:
 producing hydrocarbons from the subterranean formation. 
 
     
     
       9. The method of  claim 1  wherein the wellbore is at least one selected from the group consisting of a deviated wellbore, a highly deviated wellbore, a horizontal wellbore, and a hybrid wellbore. 
     
     
       10. The method of  claim 1  further comprising:
 activating the tackifier by degrading the degradable surfactant. 
 
     
     
       11. The method of  claim 1  further comprising:
 activating the tackifier by dissociating the degradable surfactant from the delayed-tackifier coated particulate. 
 
     
     
       12. A method comprising:
 producing a delayed-tackifier coated particulate by dry-coating a particulate with a tackifier and a surfactant simultaneously; 
 producing a treatment fluid that comprises an aqueous base fluid and the delayed-tackifier coated particulate; 
 introducing the treatment fluid into a wellbore penetrating a subterranean formation; and 
 forming a particulate pack within the subterranean formation, wherein the particulate pack is a gravel pack along a portion of the wellbore, a proppant pack within a portion of the subterranean formation, or both. 
 
     
     
       13. The method of  claim 12  wherein the wellbore is at least one selected from the group consisting of a deviated wellbore, a highly deviated wellbore, a horizontal wellbore, and a hybrid wellbore.

       15. The method of  claim 12  wherein the surfactant comprises a degradable surfactant. 
     
     
       16. The method of  claim 12  wherein the delayed-tackifier coated particulate is present in an amount ranging from about 0.25 pounds per gallon to about 30 pounds per gallon of the treatment fluid. 
     
     
       17. The method of  claim 12  further comprising:
 introducing a pad fluid into the subterranean formation before introducing the treatment fluid, wherein introducing the pad fluid is at a pressure sufficient to create or extend at least one fracture in the subterranean formation.
